I would not say better or worse, I do know the HT5000 was a step above the original Lumis. I owned an HT5000 and moved on to a Titan 1080P3d dual ultra contrast which I liked a lot better by a very large margin.ln addition the Titan had important features that the HT5000 did not..
The Lumis was compelling with dynamic black (dynamic Iris). Some see artifacts with dynamic black, most do not. The Lumis does dynamic black extremely well. Some critical viewers prefer the look of a fixed aperture. \Its all about trade-offs. The original Lumis had less than half the lumens, no 3D, and no lens memory. The Super Lumis is a major upgrade to the Lumis line. Different strokes for different folks.
